The short answer would be yes.

The longer answer is to ask 'What are you expecting that to do?'

If you expect the handshake to take place automatically then no.  The 
status and control pins on UART1 must be driven and read by the SW as 
appropriate.  In fact the only advantage really is that the status pins 
will provide an UART based interrupt.  The control pins have to be set by 
the SW when you want them to change.  It's the standard configuration in 
that family of UARTs since the 8250 when they were added mainly so that a 
single chip could handle the whole serial port.
